Use this kit when replacing stripped out OEM Pulley. It is higher quality, lighter weight, and has about double the contact area on the splines. Fast shipping and all the part you need, Also order a Gasket set for reinstalling the primary and you will need the special 1 7/8" deep socket to remove and install pulley. Good luck.
Fantastic product, manufactured to very high standard with exceptional quality. Great value for money product over stock item. A nice little performance upgrade gained by installation along with BDL 2" primary drive system.
